I was reading an article the other day about scientists studying dust devils in Nevada. The reason was to find out what causes them and what conditions do not cause them. This information would then be helpful for unmanned or manned missions to Mars. Since Mars has huge dust devils that can cause equipment failure or be a detriment to astronauts.
To get to my point, the article said that that whole area had been a large sea. In fact, most of the south west was once under a large sea. I know it was where I live now and when I lived up north of Fort Worth; you could find sea shell fossils in the shell on the hill sides.
Nevada was under water and most of Texas, so too where most of the states in between. So why, I wonder, is it mostly desert now? Where did all the water go?
From what I understand, and I could very well be wrong, the earth does not loose water vapor into space. Water is being created whenever any hydrocarbons are burned. So, where is all the water?
Some people try to tell us that because of global warming, our coastal areas will be flooded. As I see it, a huge percentage of the North American continent was under water at one time and even if all the ice in the world would melt, it would not even come close to what was under the seas of old.
What could possibly tie up all that water? How about plants? Maybe back when the south western US was under water, there were very few plants on earth. Now vegetation is almost everywhere and plants hold a lot of water. But I don’t think they could even hold a fraction of the water needed to produce the seas of ancient times. Anyway, I think that there were plenty of huge plants back then.
Well, here I am again asking a question I can’t answer. There must be some knowledgeable people out there who can explain this to me. Of course when you do explain it to me, please use small words. . .
